5.4 Adjusting the CaviBlaster
®
for Maximum Performance
The pressure at the nozzle of the lance has to be maintained within certain limits
to achieve cavitation and for best performance results. If using a calibration
pressure gauge situated between the pressure hose and the CaviBlaster
®
lance,
the water pressure should be 4,000-psi (275 bar) with the lance submerged and
the hydraulic power unit operating. For best results, repeat this calibration
procedure if cleaning performance degrades, or every 3 months at a maximum.
To calibrate the pressure at the lance, follow the procedure below:
- Stop the hydraulic power unit to discharge any residual pressure in the hose
lines.
- Disconnect the lance from the main hose line.
- Attach the calibration gauge between the main hose line and the lance and
tighten the JIC connections. (See Figure 5.1)
- Submerge the lance. Because of the danger of the operator coming in contact
the water stream from the cavitating nozzle,
CaviDyne
TM
does NOT
recommend calibrating the lance out of the water. Use extra care to avoid the
water stream if doing so.
- Ensure that the cavitation nozzle is
pointed away from the diver’s or
operator’s hands, arms and body.
- Start the hydraulic power unit.
- Hold the lance tight and observe the calibration gauge (See Figure 5.1).
- Turn the knob on top of the pressure regulating valve until pressure reads
4,000-psi (275 bar) on the calibration gauge. Turning the knob clockwise will
increase the pressure and turning it counter clockwise will decrease the
pressure.
A CALIBRATION GAUGE IS RECOMMENDED WITH EVERY
UNIT. CONNECT BETWEAN THE END OF THE HOSE AND
THE LANCE.
